This name derives from the Celtic “brig-o > brígh”, meaning “exalted one, fire goddess, power, strength, vigor, virtue”. Its popularity, especially in Ireland, is largely related to the popularity of Saint Brigid of Kildare, who was so popular in Ireland she was known as "Mary of the Gael". This saint took on many of the characteristics of the early Celtic goddess Brigid, who was the goddess of agriculture and healing and possibly also of poetry and fire. One of her epithets was "Brigid of the Holy Fire". Bridget of Sweden (1303–1373) (Swedish: den heliga Birgitta or Birgitta Birgersdotter), was a mystic and saint, and founder of the Bridgettines nuns and monks after the death of her husband of twenty years. She was also the mother of Catherine of Vadstena. She is one of the six patron saints of Europe, together with Benedict of Nursia, Saints Cyril and Methodius, Catherine of Siena and Edith Stein.
